Your Mac provides several tools to help you identify it. The simplest is About This Mac, available by choosing About This Mac from the Apple () menu in the upper-left corner of your screen. The other is the System Information app. Learn how to use these tools to identify your Mac.
If you don’t have your Mac or it doesn’t start up, use one of these solutions instead:
- Find the serial number printed on the underside of your Mac, near the regulatory markings. It’s also on the original packaging, next to a barcode label. You can then enter that serial number on the Check Coverage page to find your model.
- The original packaging might also show an Apple part number, such as MNYF2xx/A (“xx” is a variable that differs by country or region). You can match the Apple part number to one in the list below to find your model.
